PAVEMENT can be molded in a plastic state and afterward allowed to'set, and in means for uniting such blocks, so as to form structures of any ydescription which may be formed from such blocks.

My invention consists in a novel formation of the blocks, and in theI combination therewith of means by which they may be united.

It also includes details of construction, which will be more fully explained by reference to the accompanying -dra\\\'ings, in whichw Figure 1 is a perspective. view of the device. Fig. 2 shows a `forin`of arrangement.

The blocks A are made as shown, having substantially parallel top and bottom faces, and the sides made V-shaped with a central neck 2 of smaller diameterI than the top and bottom faces. The bottom faces are sufficiently wider than the top faces of the blocks, so that when the blocks arc laid side by side with the lower edges in contact, a groove or channel 3 is left between the upper parallel edges. ll'hen the blocks are thus laid, rectangular spaces Ll are formed between tlxe.contiguous blocks, by reason of the V-shaped indentatious of the sides. These spaces serve for the reception of interlocking bars or ties 5, which bars may be made of any suitable material. I

material which willset or harden. and suehfI with each other, and the joints of each abut-` tingpair of blocks may stand opposite the sldes of contiguous blocks, so that they breakejointa.` As the blocks are laid, the

uniting bars or ties 5 may be inserted, and when 'the series of blocks have been laid with these-uniting bars or ties, a 'filling 'of plastic material maybe introduced into the open channels 3, so as to fill in around the bars 5, and thus make a solid unitary structure.

If used as a pavement, it will be Aeen that the bars 5, interlocliing with the b .cks, and connecting any number of them, will prevent the blocks settling one below another, so as to become irregular; and if the outer edges of the blocks are supported by .rigid abutting sides, such as the curbs of a street, it will be manifest that the whole system will be so inter-locked as to become a practical unitary structure, and will not be rendered irregular by settling. The reinforcing rods extending through the key-bars will prevent the breaking of said bars by shocks or strains.

llavingithus described my invention, what I claim and desire to secure by Letters Patent is l. A pavement consisting of molded rectangular blocks having approximately even .the blocks being made wider than the top faces, and rectangular m' 'ded bars extending from end to end of th blocks and fitting loosely in said channels, and a filling of cement around the bars.

2. A pavement consisting of molded blocks having a length equal to a plurality of diametcrs, and having V-s'haped channels in their long sides, said blocks being laid to break joints at the, ends, and having their bottom faces of greater width than the top faces whereby the groove or channel is left between the upper parallel edges of adjacent blocks, key-bars having longitudinally embedded reinforcing rods, said bars extending across the joints of the blocks forming a loose (it with the channels, and a filling of cement around the bars.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IHSSGS.
